Method and arrangement for interconnecting hydroelectric pumping-up power system

ABSTRACT

Interconnection of a plurality of hydroelectric pumping-up power systems is achieved by providing two groups of pumping-up hydroelectric power plants on respective sides of a mountain and by accommodatively transferring water thus pumped up between water reservoirs provided at the highest levels on respective sides of the mountain through a corresponding number of water tunnels or the like, and the water thus transferred can be utilized for various purposes in addition to hydroelectric power generation.



1. A method for interconnecting a plurality of pumping-up hydroelectric power systems disposed on respectively different sides of a mountain, comprising pumping-up water successively into water reservoirs of higher levels provided on the sides of the mountain during an offpeak time of a system, and accommodatively transferring water from one of the systems to the other through a water tunnel or the like provided between water reservoirs located at the highest levels of the mountain for the respective hydroelectric power systems.
 2. An interconnecting system of a plurality of pumping-up hydroelectric power systems disposed on respectively different sides of a mountain, comprising groups of pumping-up hydroelectric power plants provided on the corresponding sides of a mountain and a tunnel or the like provided between the highest level water reservoirs belonging to respective hydroelectric power systems, whereby water can be accommodatively transferred from one of the hydroelectric power systems to another through said water tunnel or the like.
